Primary Outcome Measures :
  1. The primary efficacy endpoint is "Treatment Success," a static endpoint assessed at Day 29 after initial PH-10 treatment and defined as 0 or 1 on all Psoriasis Severity Index (PSI) components and 0 or 1 on the Plaque Response scale. [ Time Frame: 28 days ]
  2. The primary safety endpoint is incidence of adverse experiences, including pain and dermatologic/skin toxicity (incidence, severity, frequency, duration and causality). [ Time Frame: 8 weeks ]

Secondary Outcome Measures :
  1. Psoriasis Severity Index (PSI) score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ]
  2. Plaque Response score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ]
  3. Pruritus Self-Assessment score changes at each visit from Day 1 pre-treatment. [ Time Frame: 8 weeks ]
